TESTING ON PRODUCTION OF VANADIUM-MICROALLOYED HSLA STEEL WITH OVER 550 MPa STRENGTH IN CSP
-
摘要: 为在CSP线利用V微合金化加控制轧制生产550MPa以上高强度HSLA钢,通过试验钢的成分设计、模拟CSP连铸、试验轧制和Gleeble试验,初步确定了该产品在CSP线的生产工艺,为下一步深入研究CSP线的V微合金化行为奠定了基础。Abstract: In order to produce HSLA steel which tensile strength exceeds 550 MPa on CSP line, chemical composition design, CSP continuous-casting simulation, rolling test and Gleeble experiment were carried out. The effect of vanadium-microalloying and controlled rolling & controlled cooling technique was investigated. The production process was drafted and this is the base for further investigating on vanadium-microalloying behavior on CSP line.
